B. Smith recently vanished without a trace in New York City. She wandered the streets of Manhattan for 17 hours. She turned up at a coffee shop on the city's West Side. A friend happened to see her or she could have gone missing for even longer.

Her husband, Dan Gasby told the Senate, "I have seen a woman who virtually could do everything and now has to wait for people to help her."

She made a public service ad for The Brain Health Registry, and hopes her appearance in Washington will raise awareness about this dreadful disease.
